Description
Technical Field
The invention relates to a pipeline repairing device and a repairing method for a grouting lining, in particular to a construction method for a grouting lining of a lining flexible plastic pipeline and a lining construction device.
Technical Field
At present, in pipeline construction at home and abroad, a technology for lining a plastic pipe (namely lining pipe) in a pipeline is very common, and the technology comprises all fields using the pipeline, such as mines, petroleum, coal, municipal administration and the like. The method can not only improve the service life and performance of the newly-built pipeline, but also repair the inner lining of the old buried pipeline which is scrapped for a few times, so that the old pipeline can meet the use requirement again. Thereby saving a large amount of new construction cost. In the work of lining the plastic pipe in the pipeline, how to select a lining method suitable for the pipeline needing to be lined with the plastic pipe is a key problem for continuously optimizing and improving the construction method of the lining plastic pipe, so that the pipeline lined with the plastic pipe can achieve the expected use purpose and can save manpower and material resources in construction. At present, there are many methods related to lining plastic pipes at home and abroad, and the common technology is as follows: 1. the constant diameter compression technology is that special equipment is used on site to reduce the radial size of the plastic pipe temporarily and then the plastic pipe is drawn into the pipe to be lined, and then the outer diameter of the plastic pipe is tightly attached to the inner wall of the original pipe through self elastic expansion and recovery. 2. The deformation technology of the lining pipe is that the pipe body of the lining pipe is folded, deformed and bound to reduce the cross section area of the lining pipe, the lining pipe is pulled into the pipe, the plastic pipe entering the pipeline to be lined is pressed into the plastic pipe to compress air, the plastic pipe is enabled to damage the strapping tape by utilizing the pressure in the pipe and then recovers the original shape, the technology also has the problems faced by the constant diameter compression technology, and the risk that the bound lining pipe cannot be completely recovered in the pipeline to be lined is increased. 3. The lining of resin lining hose is different from plastic pipe in that the resin is adsorbed onto felt material and cured via heating, ultraviolet irradiation and other modes. Although the above-mentioned pipe lining technology solves a large number of pipe lining projects and is also accepted by the wide pipe sector, it is not a perfect lining technology. The problem to be solved is that the inner lining pipe used in the same pipeline can not change along with the change of the inner diameter of the pipeline to be lined, the part which is tightly attached is the same as the outer diameter of the inner lining pipe, the inner diameter of each pipeline to be lined (particularly a concrete prefabricated pipeline) is different, if the inner diameter of the pipeline to be lined is larger than the outer diameter of the inner lining pipe, a gap can be generated between the inner lining pipe and the pipeline to be lined, the requirement of tight attachment can not be met, the inner lining pipe which can not be firmly attached to the inner wall of the outer pipe can continuously change along with the pressure of medium in the pipe, and the inner lining pipe can be fatigued for a long time, so that the. This condition is a significant percentage of the time during pipe lining operations. The method has the advantages that field investigation is concerned, if the pipeline to be lined is built by splicing concrete prefabricated pipes with short sections, the diameter error of the inner wall between the pipe sections is about 4-6%, the diameter error of the pipeline under the condition becomes larger along with the increase of the diameter, the manufacturing outer diameter of a plastic pipe of the lining becomes difficult to determine, if the lining pipe manufactured with large diameter meets a small-diameter pipe in the construction process, great difficulty is caused, and if the lining pipe manufactured with large diameter meets a small-diameter pipe, a large gap is generated. At present, in order to solve the technical problem, in the pipeline lining construction, a scheme of adding slurry between the lining pipe and the pipeline gap appears, for example: 1. invention patent 201710236481.X "a method for filling and grouting for repairing a pipeline"; 2. patent 201301671084.7 entitled "mixed cement slurry for grouting and pipe structure", discloses an invention patent for grouting the inner wall of a lining pipe by perforating holes in the lining pipe in example 1, and discloses a grouting structure for a pipe together with the material for grouting the pipe in example 2. However, as shown in the patent of the invention disclosed in example 1: the inner wall of the lining pipe is perforated without damaging the integral structure of the lining pipe, so that the lining pipe is easy to leak at the perforating position, and the small-sized pipeline is relatively difficult to operate. Example 2 the invention patent discloses only a grouting material and a pipe structure, but there is no description as to how this pipe structure can be achieved. In order to overcome the problems of the lining pipeline and enable the technology to be better applied, the invention aims to provide a lining method and a lining device of a lining pipe, which is a simpler and more reliable grouting application technology added to the pipeline lining industry, so that the technology of an underground pipeline passing through the lining is more reliable.
